19.6 ANNUAL INSPECTION/SERVICE

It is recommended that the furnace be inspected annually by a qualifi ed installation contractor, service agency
or fuel supplier. Your annual inspection will normally cover the following:
HEAT EXCHANGER - The heat exchanger should be inspected for corrosion. The fl ue passages (heat exchanger
tubes) should be free of scale or excessive corrosion.
BURNERS - The burners should be inspected to ensure that they are free of deterioration.
CAUTION
!
!
BE CAREFUL WHEN WORKING ON THE BURNER ASSEMBLY. THE HOT SURFACE
IGNITER IS FRAGILE AND CAN BREAK EASILY.
The fl ame sensor should be inspected and cleaned with fi ne steel wool or Scotch-Brite™ scrubbing pad. The
wiring connection should be checked to ensure that it is tight and corrosion free.
DRAINAGE - The condensate drainage system should be inspected and cleaned if necessary. If the drain trap
assembly, or any other component becomes blocked, condensate may backup into the secondary or primary
heat exchanger causing nuisance trip-outs of the pressure switches or roll out switch. The condensate should
be observed for signs of dirt, carbon, debris, etc.
CIRCULATING FAN - The condition of the circulating fan should be checked to ensure that it is free of
excessive dust buildup, debris, etc. The mechanical fasteners should be inspected and checked for proper
tightness and parts alignment. The motor ventilation ports should be cleaned if necessary to prevent restriction
to cooling by air over the motor.
ELECTRICAL - All electrical connections should be examined to ensure that they are tight and corrosion free.
Repair any connections that have become loose or corroded.
FURNACE OPERATION - The furnace should be cycled during the annual inspection and servicing to:
1. Test all safety related controls.
2. Determine that the temperature rise falls within the range shown on the appliance rating plate.
3. Ensure that the burner ignition is smooth and that the fl ames are smooth soft blue, and not impinging on
the heat exchanger.
UV LAMP - The UV light should be checked after 1 year of continuous run or 9,000 hours of operation. Replace
bulb when necessary.
